Kelly Clarkson was in an upbeat mood in London Thursday despite RadarOnline.com's report that she could be putting her well-being at risk if she doesn't shed some weight.
Kelly Clarkson wore a patterned blouse and sunglasses, as she smiled for photographers while appearing at BBC Radio Thursday.
The "A Moment Like This" singer shows off her moves outside the station, a day after RadarOnline.com's shocking chat with Dr. Stuart Fischer, who hasn't ever treated the crooner.
The doctor estimated the "Since U Been Gone" singer is tipping the scales at "well over 200 pounds" -- a 60-to-100 pound increase since she captured American Idol's first crown 13 years ago.
Clarkson's singing voice might benefit from the extra girth, according to the doctor, "but it will not help her health."
The resilient celebrity's body issues could put her at risk "for 65 different illnesses, including multiple cancers in women," Fischer, who wrote The Park Avenue Diet, told us.
The 33-year-old Texas native shows off the freshly-shorn side of her head in this shot.
The "Heartbeat Song" beauty, who gave birth last year to daughter River Rose, previously told Britain's Closer magazine she knows "will take a long time to lose" the baby weight she's gained, and is just fine with that.
American Idol's first champion told Redbook last month of her physical issues: "There are just some people who are born skinny and with a great metabolism -- that is not me."
